What types of people need to be aware of when a heart attack can induce sudden death?

For myocardial infarction, although it has a rapid onset, it is often cumulative when it comes to its development, and they all occur under the influence of some long-term bad lifestyle habits and other factors. So here should be a wake-up call for this part of the people with bad habits.

1. People with chronic diseases

Often patients with myocardial infarction suffer from certain chronic diseases for a long time, such as atherosclerosis, hyperlipidemia, etc. The development cycle of these diseases is long, if there is no timely prevention and prevention in daily life, then these diseases will induce the occurrence of myocardial infarction with the increase of time.

Many people ignore these diseases because they progress slowly and have no obvious symptoms on weekdays, but know that if a heart attack occurs, it is a matter of seconds.

Therefore, those who have suffered from cardiovascular disease for a long time are also asked to have regular check-ups and timely check-ups.

2. People with bad habits

These bad habits come from many aspects, such as daily diet, daily work and rest habits, and so on. Once these bad behaviors become habits, they will increase the occurrence of myocardial infarction in the long run.

Especially in the daily diet, some people like to eat high-oil food, although the mouth and stomach are enjoyable, but these high-oil things will lead to an increase in viscosity through absorption into the blood, and the blood is viscous and easy to form blood clots, thereby inducing the appearance of myocardial infarction.

There are also some people who love to drink, and they feel uncomfortable if they don't drink a meal, and everyone knows that regular drinking is harmful to health, but if they want to quit drinking, they will say a bunch of prevarications, such as who has drunk all their lives and has not seen a heart attack. That being said, there is a matter of probability here, and it is clear that there is a higher chance of heart attack from long-term drinking.

Some people will say that drinking alcohol doesn't make the blood diluted? But also know that alcohol concentrates the blood! And long-term heavy drinking can lead to coronary artery spasm, know that this blood vessel is responsible for the blood supply to the heart! Therefore, it is also hoped that people who drink alcohol should drink as little as possible or stop drinking.

3. Miscellaneous

When it comes to heart attack, everyone will say that it is because they don't exercise on weekdays. It's true that regular exercise is beneficial, but it must be done in the right way.

Some of the induced myocardial infarction is also caused by exercise, especially for people with chronic vascular diseases in the past, they want to be healthy, so they choose exercise.

But for these people, exercise is okay, but there must be a degree, and you must know that it is not that the greater the amount of exercise, the better, and the longer the time, the better.

For example, if some blood clots fall off during exercise, then it is likely to block the blood vessels supplying the heart, which will induce myocardial infarction, and such cases abound.

Don't be angry on weekdays, especially those who have a history of cardiovascular disease in the past, knowing that anger can lead to vasospasm, which can easily induce myocardial infarction.

The above-mentioned groups of people also hope to pay special attention to the fact that no matter what disease is the first priority is prevention, only prevention can minimize the incidence of myocardial infarction.

Patients with myocardial ischemia, patients with arrhythmia, it is recommended to maintain a good sleep, do not lose your temper, reduce work pressure, the cause of sudden cardiac death is caused by insufficient blood supply to the heart or poor physical fitness.

People with high blood pressure and strong work ability, because their physical fitness is not good, can easily induce heart attack.

People who often stay up late, people with irregular work and rest, and people who overeat should pay attention to it, which is easy to cause myocardial infarction and induce sudden death

Most of the causes of myocardial infarction are due to coronary atherosclerosis, plaque formation, causing narrowing of the lumen of blood vessels and thus causing myocardial infarction, the prevention of patients is to prevent blood vessels from growing plaques, and at the same time control plaques through drugs, diet and lifestyle changes in the case of small plaques, so that plaques can be reversed, smaller, or prevent plaque growth, so that plaques become firm and not easy to rupture, and they should be treated with a light, low-fat diet to control cholesterol and LDL levels in the body.

It is mainly because of the thrombosis in the blood vessels, and the plaques have obviously fallen off, forming embolism, which blocks the blood vessels and causes myocardial infarction; Usually eat some light food, don't eat some greasy food, and eat a low-salt and low-fat diet.

For young people nowadays, their lives are also very irregular, because they usually often stay up late to look at their mobile phones, and they also play games and go to dinner from time to time, which is a very obvious problem, because for young people, if their lives are irregular, it is likely to cause greater harm to the body.

Therefore, we usually pay attention to the diet and don't have to eat things with high blood lipids and high blood sugar, which is not very good for the body, and you can't stay up late to look at your mobile phone. Therefore, the usual diet and matching also have the rules of life, and you must adjust it well, and you must not joke about yourself.

Don't overeat, stay up late often to play on your phone or play games. Meals also need to be dominated by a light diet, and you don't have to eat high-lipid, high-fat things. Therefore, for the current young people, the vast majority of young people, their life rules or bad, for the usual life must be good to protect their body, do not have to stay up late, let alone overeating, there is also a bathing process can not, after eating to take a shower, this is also very bad for the body, because after eating enough to take a shower, the inside is more stuffy, which will also produce high blood, high heart attack.

Therefore, it is very scary for this disease, because once the disease here comes, it is very likely that it will not be cured.

And if we don't standard our own schedule and stay up late for a long time, it is very likely to cause myocardial infarction, and excessive work pressure will also cause myocardial infarction. Nowadays, everyone is living in a very rapid and progressive society, and the reasons for each person's myocardial infarction will be different, and there are many people who have myocardial infarction at present. This is also mainly due to the high pressure of social development, everyone may be overtired, and there is greater work pressure, mood swings are also very large, including the wrong place to settle in the diet is not good.

Frequent smoking, frequent drinking, frequent late nights, particularly stressed, and frequent anger can induce heart attacks.

Often stay up late and work overtime, irregular living habits, due to excessive pressure, overtime insomnia, the pace of life is too fast, resulting in excessive mental pressure will make the body secrete a large amount of adrenaline, resulting in vasoconstriction and sympathetic nerve excitement.

Heart infarction and cerebral infarction are words that sound desperate, once you have this disease, you can't get rid of their shadow in this life, and you may be killed at any time. Many people may think that myocardial infarction and cerebral infarction are far away from them, that they are still very young, or that their blood pressure, blood lipids and blood sugar are still normal, and they will not get this disease at all, but this is not the case.

An important cause of blood vessel blockage is the accumulation of fat in the body, forming hardening and even plaque, so the key point of prevention is to prevent fat deposits, that is, to reduce as much as possible the low-density lipoprotein that transports fat into the endothelium of blood vessels. According to studies, for people who have formed plaques or hardening, as long as the LDL is controlled, the plaques that have formed will stop growing, which can effectively prevent the occurrence of myocardial infarction and cerebral infarction. The damage to blood vessels is great, and it will greatly increase the chance of disease, so the three highs should be well controlled, and low-density lipoprotein should also be controlled.

Because LDL is synthesized by the liver, staying up late, abusing drugs, and eating and drinking will damage the liver, and if you don't fundamentally change your living habits, LDL is impossible to control well.

The incidence of myocardial infarction is higher in men over 40 years old and women over 50 years old, and in recent years, the probability of myocardial infarction in young people has gradually increased, which has a lot to do with daily habits. The pressure of working during the day is high, coupled with the need to work overtime at night or have a supper with the boss, there is very little time to sleep every day, only 5 hours, or even shorter, the body is tired for a long time, coupled with lack of sleep, and the immunity in the body is low. If you continue to be in such a stressful, exhausted and nervous state, even if your body is healthy, you will have a day that you can't bear it, and eventually you may induce the risk of myocardial infarction.

Therefore, it is important to organize your working hours well and not overwork yourself.

During holidays, people often go out to eat, although this is human nature, but everyone should pay attention to control the amount of oil they eat. If you consume too much at once, foods that are high in fat, calories and protein. It can easily lead to an increase in the body's blood lipid level, resulting in an increase in the thickness of the blood, which in turn blocks the blood vessels and increases the occurrence of myocardial infarction.

Therefore, no matter what time it is, for your own health considerations, it is better to consume in moderation.

Don't have too much pressure at ordinary times, be sure to rest well, don't stay up late, go to bed early and get up early, exercise more, and eat a light diet.

Don't sulk too often, have regular physical checkups, pay attention to your physical condition, and pay attention to the combination of diet.

In recent years, with the development of drugs and the promotion of revascularization technology, the prognosis of acute myocardial infarction has been significantly improved, but there is still a high mortality rate, and among these deaths, sudden cardiac death is the most important mode of death, accounting for 24% 40% of all deaths. Therefore, in the management of acute myocardial infarction, we should pay attention to the prevention of sudden cardiac death.

Guideline-recommended lifestyle interventions, optimal medications**, and revascularization are effective means of preventing sudden cardiac death after myocardial infarction, but these are not sufficient for some high-risk patients. Today we are going to talk about another "magic weapon" to prevent sudden cardiac death - implantable cardioverter-defibrillator (ICD). In general, the indications of ICD in the prevention of sudden cardiac death after myocardial infarction can be divided into primary prevention and secondary prevention.

40 days after myocardial infarction ICD implantation 90 days later

The so-called primary prevention is mainly for patients with myocardial infarction who have not had malignant arrhythmic events but are at high risk of sudden death. Left ventricular ejection fraction (LVEF) is by far the most important indicator of risk stratification of sudden cardiac death after myocardial infarction, so guidelines recommend that the indications for primary prevention of ICD are:

At least 40 days after myocardial infarction without revascularization, at least 90 days for revascularization, LVEF 35%, cardiac function grade II or III;

No revascularization for at least 40 days and revascularization for at least 90 days after myocardial infarction, LVEF 30%, cardiac function class I.

However, in fact, because of the fact that only 1 3 patients with ICD have played a role in primary prevention, some scholars have proposed the concept of primary prevention, that is, primary prevention plus one or more of the following:

non-sustained ventricular tachycardia;

frequent premature ventricular contractions (10 hours);

lvef＜25%；

Syncope or presyncope.

The recently announced IMPROVE SCA study validates the clinical value of the indications for prophylaxis.

The study, which included 3889 patients with indications for prophylaxis, compared the effect of ICD implantation on all-cause mortality and showed a 49% reduction in all-cause mortality in patients who received ICD implantation compared with those who did not at 21 months of follow-up.

How to deal with sudden death before ICD implantation?

In addition, I think everyone should note that the above indications for primary prevention all emphasize that the ICD is implanted 40 or 90 days after myocardial infarction, so how can we prevent sudden cardiac death in patients during this period?

First, ICD implantation within this time window is not recommended, based on the negative results of two clinical studies, DINAMIT and IRIS, which found that early ICD implantation in acute myocardial infarction only reduced arrhythmic deaths, but did not improve overall mortality.

Second, for high-risk patients within this time window, there are guidelines recommending the consideration of wearable ICDs, but a recent VEST study published in the New England Journal (NEJM) suggests the opposite.

Myocardial infarction is extremely critical and has a high mortality rate. Only timely recanalization of occluded coronary arteries and reperfusion of ischemic myocardium can reduce the risk of propulsion and mortality. Myocardial infarction is caused by a sudden interruption of blood flow in the coronary arteries, resulting in persistent ischemia and hypoxia of myocardial cells.

Acute myocardial infarction is mostly based on coronary atherosclerotic stenosis, unstable plaque rupture, thrombosis, with or without coronary vasospasm. It leads to a sudden and persistent interruption of coronary blood flow, causing necrosis of myocardial cells, which is a critical cardiovascular disease and requires urgent vascular recanalization. Regular medication is used to control and reverse myocardial remodeling, control the occurrence and development of the disease, reduce complications, and reduce the risk of death.
